Spiral classifier and hydrocyclone are the main equipments for the classification operation of the concentrator. Although the rapid development of the cyclone once made the spiral classifier lose its market, but with the continuous changes in the requirements of the selection plant, it was found that the spiral classifier also has its advantages

Operation. The machine can only be operated after the structure and working principle of the spiral classifier are clear. After the spiral body rotates, it can start to feed ore slurry, gradually feeding the amount of ore. When the spiral body is in working state, if it encounters special faults such as jamming or overload), it must be stopped

Spiral pitches (single / double / triple): Number of ribbons is a factor in controlling degree of agitation. Each ribbon of advanced pitch gives greater raking capacity than equivalent ribbon of spiral using lesser pitch. Triple ribbon spiral highly advantageous for slow-speed operations requiring close separations and high raking capacities

The spiral classifier has the advantages of simple structure, stable operation and easy operation. It is also its simple operation process and stable working state, which not only greatly reduces the maintenance and replacement cost, but also ensures the construction time and ensures the hierarchical operation

High spiral classifier operation: the grinded pulp is fed into a tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low-speed rotation stirs the slurry, so that the fine particles rise, and the coarse particles sink to the bottom of the tank

May 06, 2012 May 06, 2012 Spiral classifier operation and machine upkeep. Among the mining machinery, addressing machine is an important category. Now, the author will let you know one of the addressing equipments, spiral classifier. The structure of the spiral classifier, semi-circular sink, steel plate and steel welded into the feed inlet in the middle of the tank sidewall, the lower part of the tank

May 26, 2016 Spiral Classifier. In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow

Mar 26, 2016 The Humphreys Spiral Concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity. This concentrator is a spiral conduit of modified semi-circular cross-section, with outlets for removal of concentrate and middling

DOVE Spiral Classifiers are designed with special totally enclosed submerged bearing at the spiral real shaft end, providing efficient operation with low maintenance. DOVE classifier is designed with special curved false bottom plate, to achieve absolute minimum clearance between the screw and the tub, therefore reduce slippage and maintain the

Aug 06, 2015 Spiral Classifier for Mineral Processing. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn’t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do

High Weir Spiral Classifier. Introduction. Classifying equipment takes use of the different sedimentation speed of the solid particle in slurry. Capacity. 10～1785 t/d. Product improvement. An automatic elevating apparatus is added to the discharge opening. The scoop in ball mill is eliminated bringing more stable operation

spiral classifier operation. Spiral classifiermineral processing spiral classifier spiral classifier is widely used in mineral processing plant to form closed cycle way with ball mill for split mineral sand or used in gravity concentrator to grade ore and fine mud or the size grading of slurry in ore dressing process as well as desliming dehydration and other operations in ore washing operations

Metso The spiral classifier is widely used in the classification of the grinding circuit of the concentrator and the operations of washing, desilting and dewatering. Its main advantages are simple equipment structure, reliable work and convenient operation. 1
